- Empathy Hydrangea Biofertiliser with Rootgrow™ is a targeted plant food specifically tailored to the needs of hydrangea plants in the garden.
- Hydrangeas planted directly into the ground benefit from the treatment for the first three to five years whilst their root system and fungal partners develop. Apply twice yearly.
- Apply on both container-grow hydrangeas and those grown in the open ground to improve flowering, optimise nutrient uptake and aid overall health and vigour.
- Safe and easy to use, simply sprinkle the biofertiliser around the base of your hydrangea, gently fork it into the soil/compost and then give a watering.
- This product has been endorsed by the Royal Horticultural Society thanks to its trusted, reliable performance across UK gardens.
